possible, but nothing i can confirm

 

evga's lineup is confusing lol

Wait until they'll introduce three-letter lineup names.

i checked a review on it a while ago

https://www.techpowerup.com/review/enermax-epm1200ewt/

it's good, but dated... seems around 9 years old now

Hmm,cant find the exact model. It is semi modular with main cables being ketchup and mustard,but the rest are flat black,so i guess its not the oldest one.

it seems to be the one that got linked here by @Juular to my eye, so probably the one i linked as a review

 

so again, good, but dated

Hey folks!


I'd like to ask a few things just to become wiser when it comes to PSU's, but I thought I'd add a little context first. I'm a bit confused and I've been looking at this newer tier list (I used to keep an eye on the older one) trying to understand the criteria, at least generally, for noobs. At a quick glance it seems like the Corsair AX series ranked lower in this one compared to the old list, I'm mostly looking for a 1000W/850W (in case there's no cheaper option for the former) so it caught my glimpse; I was just reading through Aris' reviews on TH and apparently the AX1000 has gotten a pretty recent revision.

 

With that in mind:
- why would Corsair HXi be recommended over the 2018 AX revision for multiple GPU setup?

- how come the V Platinum is a top recommendation now with their new version?

- would a more recent production PSU offer any advantage for Zen2 cpu's, taking into account that amd handles system idle totally different now? Also, would their "race to sleep" implementation have any impact on sub 10% loads when it comes to general efficiency?

 

Thank you for your time!

Because it's multirail, it's not exactly a requirement but good to have, see it as yet another protection feature.

Any relatively modern PSU with independent regulation topology would be the same here. There was a new power saving standard released recently (EpS 2.92 IIRC) but since there's just a handful of lineups that support it yet you shouldn't really choose a PSU based on it's support.

What's your specs ?

because AX is a single rail, based off the Seasonic Prime platform

because of it being a delta GM, just as the antec

not at this moment, but atx 2.52 has recently been introduced with a higher requirement for sleep states, so we might see something from that soon

@Juular Oh that's good to know, thank you! Initially I wanted to build a TR workstation, but with the crazy prices here on the new threadrippers (and the previous platform not making much sense anymore), it's a little bit too much for an entry workstation. I would probably build around a 3900x or 3950x, leaving options open towards a 3960X when next gen is out, if I reach a point where render times start being really important. I will probably be using most of the SATA ports available (up to 4xSSD 2xHDD) and for the GPU side I'm hoping to drag it out with a 1070 until a suitable replacement makes sense.

But really I would just rather have the system running cool at lower rpm, firstly to avoid noise and second for daily power savings (if I leave UE4 loading environment assets overnight, for example, I really wouldn't want the system to be holding the PSU at full load). Also the chassis isn't great in terms of ground clearance for the PSU socket, it sits barely above ground level so I would assume the fan spinning faster wouldn't be as useful.

@LukeSavenije Interesting, I've read Delta has a reputation for build quality, but I checked some in-depth reviews which pointed out the V1300 isn't doing great in transient response (3.3V) compared to many other alternatives in the same price point (V1000 would be relevant here but it's newer so I can't find any review). So I was wondering why someone would recommend it over a Corsair or EVGA with higher efficiency levels.
Btw, thank you for the detailed reply!

just to make sure... can you link the reviews to me? so i know you didn't accidentally look at the seasonic based one from 2013

AFAIK, nothing really uses 3.3V rail nowadays where slightly suboptimal transient response would matter. It's mostly RAM which isn't generating much transients and on some boards (high-end presumably) it's actually replaced by 5V rail.

All you need is a good 750W PSU then.

PSU noise (if we're talking about that) doesn't depends on the power rating of PSU really, 1200W PSU and 750W PSU on the similarly performing platforms will have the same thermals and therefore noise with the same load level.

Apologies, I actually wanted to link a few but I figured I didn't want to bother you guys with long posts.
The one I mentioned was here https://www.tomshardware.com/reviews/cooler-master-v1300-platinum-power-supply,6115.htm

 

Juular linked the other one on the 850W unit.


@Juular My knowledge is probably superficial, but I compared the load testing graphs on a few units and I assume a higher wattage unit would be more efficient if it runs at the 50% efficiency level under load. I was just trying to figure out a way to balance it out between 10% and 50% workloads so it always runs at higher efficiency.

Efficency curves of modern PSUs with LLC topology are very flat, there's like 3% difference between highest efficiency point and 20\100% load.

See these same two reviews on CM V Platinum, it's about 90% on 850W unit and 92% on 1200W one at 700W load.

But nope, these two units at least, don't have the same noise output on 700W ...

Would you have any hints on how to figure out if it's a modern topology? Sometimes it gets confusing because most vendors do not mention the release date of the units, so it's quite hard to determine if it's a refreshed unit or an older unit, especially with stocks being old across various stores, plus items have different SKU's for EU, which is another layer of complications (a good example of this is the AX line which has like 2018, 2010 etc variants, superflower's stuff looks extremely similar as well).

You have this same tier list, anything up from tier B are modern, not necessarily LLC but if you're looking at Gold\Platinum unit chances are it is. In other words, don't worry about efficiency, it's not a way to choose PSU.

 

See, if you plan to use Threadripper 3960X, it's power draw are about 300W on average, GTX1070 isn't exactly power hungry GPU but if we make some room for potential upgrade to say RTX2080 Ti which is 300W too, that's about 650-700W on average in the worst case scenario (power draw wise), likely no more than 550W in usual usage patterns. CM V850 seems a bit loud but it's more expensive at that so i don't see the point in it, if you want multirail then go for Bitfenix Whisper \ Enermax Revolution DF but Corsair RMx \ Seasonic Focus GX \ Phanteks AMP (nevermind, they're not so quiet too) would be good too.

 

@LukeSavenije Where Seasonic PRIME Gold GD & GX stand for in the tier list ? Or there's not enough data on them ?

you mean prime gold? they're not too far off from focus, but have a couple small upgrades to them

 

from the focus gx i already have data with the recent phanteks amp review, as well as the focus px review recently, though that one had a surprisingly low opp/ocp

 

i need to have more on transients in general, so I'll leave that aside for now

Yes, PRIME Gold (GX) and PRIME Gold Ultra \ SNOWSILENT (GD). With recent price spikes on PSUs in US they have rather good price to ratio buy i don't see them in the list, there's only PRIME Platinum.

Oh wow, I had previously narrowed it down to something like a HX850i or a Prime Platinum but it seems these open up a new perspective. I'm gonna google some reviews of those and do some reading. I'm avoiding the focus stuff for now because I'm quite sure local vendors have older stock and might not have the revisions, will see if I can source it somewhere else.

PS:Kudos to you for actually teaching others!

Edit: seems I have to rule out the Bitfenix Whisper as well because only caseking has them and shipping is like a third of its price.
